Matsayin hydroxypropyl methyl cellulose a cikin turmi mai laushi

MatsayinHPMCa cikin turmi mai ruwa

Turmi mai gauraya: Turmi mai gauraya wani nau'in siminti ne, mai ɗanɗano, cakuda da ruwa, kuma bisa ga halayen abubuwan da aka haɗa daban-daban, a wani yanki, bayan an auna shi a tashar haɗawa, an haɗa shi, an kai shi wurin da motar ta yi amfani da shi, a cikin wani akwati na ajiya na musamman, sannan a yi amfani da shi a lokacin da aka ƙayyade.

Ana amfani da Hydroxypropyl methyl cellulose a matsayin wakili na riƙe ruwa don turmi na siminti, da kuma famfo na turmi na retarder. A cikin gypsum a matsayin abin ɗaurewa don inganta aikace-aikacen da kuma tsawaita lokacin aiki, riƙe ruwa na hydroxypropyl methylcellulose na HPMC don kada slurry bayan bushewa ya yi sauri da fashe, yana taurare don inganta ƙarfi. Rike ruwa muhimmin abu ne na hydroxypropyl methyl cellulose HPMC, kuma shine abin da masana'antun turmi da yawa ke damuwa da shi. Abubuwan da ke shafar tasirin riƙe ruwa na turmi da aka ƙara sun haɗa da adadin HPMC da aka ƙara, ɗanko na HPMC, ƙarancin barbashi da zafin yanayin amfani.
Hydroxypropyl methyl cellulose HPMC a cikin turmi mai ruwa babban aiki ne a fannoni uku, ɗaya shine ingantaccen ƙarfin riƙe ruwa, na biyu shine daidaiton turmi mai ruwa da kuma thixotropy na tasirin, na uku shine hulɗa da siminti. Rike ruwa na cellulose ether ya dogara da ƙimar sha ruwa na tushe, abun da ke cikin turmi, kauri na layin turmi, buƙatar ruwan turmi, da lokacin saitawa. Mafi girman bayyanannen hydroxypropyl methyl cellulose, mafi kyawun riƙe ruwa.
Abubuwan da ke shafar riƙe ruwa na turmi mai danshi sun haɗa da ɗanɗanon cellulose ether, ƙara yawansa, girman barbashi da zafinsa. Girman ɗanɗanon cellulose ether, haka nan riƙe ruwa zai fi kyau. Ɗanɗanon muhimmin ma'auni ne ga aikin HPMC. Ga wannan samfurin, amfani da hanyoyi daban-daban don auna ɗanɗanon sakamakon ya bambanta sosai, wasu ma da kashi biyu. Saboda haka, dole ne a yi kwatancen ɗanɗanon ta hanyar gwaji ɗaya, gami da zafin jiki, rotor, da sauransu.

Gabaɗaya dai, yawan danko, haka nan yawan riƙe ruwa yake. Duk da haka, yawan danko, yawan nauyin kwayoyin halitta na HPMC, da kuma ƙarancin narkewar HPMC, wanda ke da mummunan tasiri ga ƙarfi da aikin ginin turmi. Mafi girman danko, haka nan kuma tasirin kauri na turmi yake bayyana, amma ba shi da alaƙa kai tsaye. Mafi girman danko, haka nan ƙarin danko mai danshi, kyakkyawan aikin gini, aikin scraper mai danshi da kuma babban mannewa ga substrate. Duk da haka, inganta ƙarfin tsarin turmi mai danshi da kansa bai taimaka ba. Duk da haka, aikin ba a bayyane yake ba a bayyane yake a matsayin anti-roba. Sabanin haka, wasu matsakaici da ƙarancin danko amma hydroxypropyl methylcellulose da aka gyara suna da kyakkyawan aiki wajen inganta ƙarfin tsarin turmi mai danshi.
Da yawan sinadarin cellulose ether PMC da aka ƙara, haka nan yawan sinadarin da ke riƙe ruwa, haka nan yawan sinadarin da ke riƙe ruwa, haka nan yawan sinadarin da ke riƙe ruwa. Haka kuma, ingancin sinadarin hydroxypropyl methyl cellulose yana da matuƙar muhimmanci.
Ingancin hydroxypropyl methyl cellulose shima yana da wani tasiri akan riƙe ruwa. A cikin yanayi na yau da kullun, irin wannan danko da kuma bambancin launin hydroxypropyl methyl cellulose, a ƙarƙashin adadin ƙari iri ɗaya, ƙarancin ingancin tasirin riƙe ruwa ya fi kyau.
A cikin turmi mai jika, ƙara cellulose etherHPMCyana da ƙarancin ƙarfi, amma yana iya inganta aikin ginin turmi mai laushi sosai, shine babban ƙari wanda ke shafar aikin turmi. Aikin turmi mai laushi yana da tasiri sosai ta hanyar zaɓin hydroxypropyl methyl cellulose mai dacewa.
